Buriscon regulated immune response in Drosophila melanogaster
(University of Missouri--Columbia, 2011)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Bursicon is a heterodimeric neurohormone which binds to the receptor LGR2 and regulates various aspects in cuticle sclerotization and wing expansion in diverse insect orders...
Molecular characterization of CLE peptide mimicry during cyst nematode pathogenesis
(University of Missouri--Columbia, 2011)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Plant-parasitic cyst nematodes establish intimate parasitic relationships with their hosts by penetrating the root as motile juveniles and migrating intracellularly until...
Life histories of two little known parasites of the apple and pear
(University of Missouri--Columbia, 1907)
The Sooty Blotch is a very common fungus upon the fruit of the apple and pear. It was first reported by Schweinitz in 1831 from Pennsylvania. Since then it has been reported from all parts of the United States and Europe. ...
Effects of soil management and plant breeding on insect herbivore growth and consumption
(University of Missouri--Columbia, 2020)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] The benefits of sustainable soil management practices on soil health have been well documented for over a century. In 2017, 42,087,306 ha of farm land were cultivated with no...
The underlying genetic control of maize root system architecture
(University of Missouri--Columbia, 2020)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Maize (Zea mays ssp. mays) is one of the most widely cultivated and highest yielding grain crops in the world. The genetic and phenotypic diversity of maize facilitate its use...
Vegetation management along roadside and railroad right-of-ways
(University of Missouri--Columbia, 2018)
to restrict weed emergence. Field studies in central Illinois (three), Missouri (one), and Kansas (one) were established in 2015 and 2016 to compare fall single versus multiple application timings of residual herbicides from fall through the following summer...
Factors that influence the movement of Cauliflower mosaic virus in susceptible and resistant plants
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Since the first description of Cauliflower mosaic virus (CaMV), it has been the subject of many research papers, both as a model system for plant molecular virology...
Horticultural crop response to synthetic auxins
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Rising adoption of dicamba-tolerant soybeans increases the potential exposure of grapes to dicamba, where off-target injury may occur via particle or vapor drift. In 2017...
Application of CRISPR/Cas9-mediated genome editing for studying soybean resistance to soybean cyst nematode
(University of Missouri--Columbia, 2016)
Soybean cyst nematode (SCN) Heterodera glycines has become one of the most economically important pathogens of soybean in the world. The main strategy of SCN management is planting resistant soybean cultivars. The main ...
Role of oxalate oxidase and apoplastic reactive oxygen species in root growth regulation in water-stressed maize primary roots
(University of Missouri--Columbia, 2012)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Previous work on maize primary roots under water stress showed that cell elongation is maintained in the apical region of the growth zone but progressively inhibited further from...
Interactions between cover crops, herbicides and weeds in soybean production systems
(University of Missouri--Columbia, 2018)
The use of cover crops in soybean production systems has increased in recent decades. There are many questions surrounding cover crops, specifically their benefits to crop production and how to best manage them. One ...
Conservation and divergence of reproductive phasiRNAs in flowering plants
(University of Missouri--Columbia, 2021)
RNAs are triggered by miR2275, and are highly enriched during meiosis in many angiosperms. In my dissertation project, I am investigating the origins and diversity in eudicots of these reproductive phasiRNAs and their role in heat stress. Here, I describe unexpected...
Top-soil root architecture characteristics of obsolete and modern soybean cultivars and shoot and seed nutrient contents
(University of Missouri--Columbia, 2020)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI--COLUMBIA AT REQUEST OF AUTHOR.] Soybean (Glycine max Merr.) is one of the most important cash crops worldwide. It is widely used to produce oil and protein for food and animal feed. Soybean grain...
Innate immunity in Arabidopsis : molecular mechanisms of HOPA1 and AVRRS4 - specific disease resistance signaling pathways
(University of Missouri--Columbia, 2009)
Plants have evolved several layers of predetermined defenses, collectively called the innate immune system. Because of its effectiveness effector-triggered immunity (ETI) is a highly valuable agronomic trait. However, ETI ...
The semiaquatic heteroptera (Gerromorpha) of Thailand : faunistics, biogeography and phylogeography
(University of Missouri--Columbia, 2008)
Semiaquatic heteropterans (Gerromorpha) were collected from mountain streams and waterfalls and lowland ponds adjacent to the mountains were collected from 2002 to 2006. One hundred fifty-eight species representing 31 ...
